Description

Improvement of penetrating sleeve post

This creation is related to the structure of a penetrating sleeve post. In more detail, it refers to a more stable positioning of the external sleeve so that it does not cause undesired falling off and affects smooth operation. The novel creation.

According to the so-called "transmissive sleeve post", it is specifically referred to as a socket type wrench (refer to the fifth figure) for vertical angle insertion, and then to the sleeve end of the sleeve post. The part is further connected with an external sleeve, and the auxiliary tool kit for turning and rotating the screw workpiece can be applied to the screw workpiece located at a deeper position.

Of course, today's conventional sleeves have the basic components such as the post body, the positioning ring, the spring and the sliding sleeve. However, since the main body of the post is provided with only one bead for external connection. The cylinder is subjected to a single point of positioning , which also leads to the use of the following items:

First, it is well known that any two objects that can be inserted into each other are not difficult to be inserted, and the basic tolerance spacing is reserved for each other, and the sleeve post and the external sleeve are divided into two separate parts. Outside the object, it may also be manufactured by two different companies, so that the tolerance gap between them will be more difficult to accurately grasp. Therefore, when only one bead is attached to the corresponding groove of the outer sleeve to obtain the locking effect, then Unexpected shedding often occurs, causing unnecessary troubles in use.

Second, most of these tools are used in environments requiring high-intensity force. Therefore, whether it is the force-applying part of the external sleeve or its groove, or the circumference of the bead, it will inevitably have a period of use after a period of use. A certain degree of wear and deformation occurs, so that the tolerance gap between them will be more enlarged, and the aforementioned unintended shedding phenomenon will occur more frequently. It is true that these conventional designs are necessary to be improved.

Therefore, in view of the above facts, the creator relies on his practical experience of practicing the industry for many years, actively betting on his efforts and actively researching and improving. This creation was born early; therefore, its main focus is on how to make an external sleeve. There is no unintended detachment from the main body of the post, which effectively maintains the smooth operation of the overall operation during construction, and at the same time, it does not cause unnecessary troubles due to such situations, and can indeed add practical value to it. The main purpose is for the purpose.

Yes, it is mainly provided at least two or more bead grooves on the outer circumference of the sleeve body end portion, so as to match the relative number of the top beads, so that it can automatically compensate for the basic tolerance spacing between the two socket members. It can make it more stable and fixed, and even allow the components to wear a certain amount of deformation at the contact surface, and it is possible to apply the best card fixing effect to the groove of the external sleeve.

In order to further understand the technical means and structural features of the present invention, a preferred assembly embodiment is described in detail with a number of drawings. First, as shown in the first and second figures, the system includes: The rod body 10 is hollow, and has a polygonal insertion portion 11 at its upper end, and a groove 12 at the proximal end, and a sleeve end 14 having a polygonal inner hole 13 at the lower end. The upper and lower edges of the sleeve end portion 14 are respectively provided with a ring groove 15 and 16; a first positioning ring 20 is sleeved on the sleeve end portion 14 of the post body 10 at the ring groove 15 a spring 30 is sleeved on the outer periphery of the sleeve end portion 14 of the post body 10 so as to be located between the post body 10 and the sliding sleeve 40, and one end thereof is blocked by the first positioning ring 20; The sleeve 40 is also hollow, and is also provided for covering the outer periphery of the sleeve end portion 14 of the post body 10, and is constantly pushed by the spring 30. Further, a sleeve is provided in the inner hole 41. a portion 42 and a drop bead recess 43; a second locating ring 50, which is sleeved at the lower ring groove 16 of the sleeve end portion 14 of the post body 10, thereby blocking the sliding sleeve 40; The components are mainly disposed at the outer circumference of the sleeve end portion 14 of the post body 10, and at least two or more bead slots 17 are provided, so as to be matched with the relative number of the top beads 60, the external sleeve can be connected. The grooved groove 71 of 70 applies the best card fixing effect as its characteristic.

In the normal state, as shown in the third figure, due to the constant holding of the spring 30, the top holding convex portion 42 of the sliding sleeve 40 pushes each of the top beads 60 into the corresponding bead groove 17 to externally connect the sleeve 70. Trench 71 The desired latching action is formed, and when the external sleeve 70 is to be released or inserted, the sliding sleeve 40 only needs to be displaced in the direction of the plug portion 11 of the post body 10 so as to be in the state shown in the fourth figure. Each of the top beads 60 will not be forced by the external force, and will slightly exit and slide into the falling bead 43 of the sliding sleeve 40 (ie, release the jam of the external sleeve 70), after the external sleeve 70 is removed or installed, The sleeve 40 will automatically return to its normal position.

It can be seen that the present invention utilizes at least two or more top beads 60 to form a multi-point jam effect by the corresponding recessed groove 71 of the external sleeve 70, which of course can meet the expected stable holding effect, and can completely eliminate the two Those who are not expected to fall off.

Looking at the above, before the application, the creation of this creation has not only been found in similar products and related publications, but also has the practical value and positive benefits of "new" and "progress". Cheng has already met the application requirements of the new patent, and it is reasonable to obtain The protection of the patent law, 提出 apply in accordance with the law.
